Rename some photo according to their metadatas failed...

[Emilien]

I use pyRenamer 0.6.0 in Fedora 20 GNOME and there is sometimes a bug if trying to rename some photo according to metadata EXIF DateTime.

This metadata exists (see attached Properties GNOME window) but pyRenamer fail to retrieve this information with the following in "Image" tab :

- Original rule : {X}.{X}
- Renamed file rule : {imageyear}{imagemonth}{imageday}_{imagehour}{imageminute}{imagesecond}.{2}

After a preview, only "_.JPG" is available instead of date displayed in field called "Date du cliché" in attached screenshot...
